It is unclear who killed Cali, who reportedly became the head of the crime organization in 2015.

The Gambino crime family is one of New York’s notorious “Five Families” and traces its origins to the early 20th century. It has been led in the past by infamous mobsters such as Carlo Gambino and John Gotti.

According to the Post, Cali steered the organization in expanding its illicit drug trade, particularly in heroin and OxyContin.

“He is everything over there,” a person with mob ties in Italy told federal agents, the Post reported last year.
